     These  factors  include  the  quantity  and  price  of crude  oil  imports,
fluctuating supply and demand, pipeline and other transportation facilities, the
marketing of  competitive  fuels,  state and federal  regulation  of oil and gas
production and  distribution  and other matters  affecting the availability of a
ready market. All of these factors are extremely volatile.

     Union Pacific  Resources  accounted for 85% and 86% of the Company's  total
sales in 1995 and 1994, respectively.  No other purchaser individually accounted
for more than 10% of such sales.  Although  the Company  marketed a  significant
portion of its sales to the above noted companies, such a concentration does not
pose a significant risk to the commodity nature of the Company's products.

Environmental and Conservation Regulation

     State  regulatory  authorities  in the states in which the Company owns net
profits  interests in  producing  properties  are  empowered to make and enforce
regulations  to prevent waste of oil and gas and to protect  correlative  rights
and opportunities to produce oil and gas for owners of a common reservoir.  Each
of such regulatory authorities also regulates the amount of oil and gas produced
by assigning allowable rates of production,  which may be increased or decreased
in accordance with supply and demand.  Requirements regarding the prevention and
clean-up of  pollution  and  similar  environmental  matters are also  generally
applicable.  The costs,  if any,  that may be incurred in this regard  cannot be
predicted.

     The existence of such  regulations  has had no material  adverse effects on
the Company's  operations to date,  and the cost of compliance  has not yet been
material.  There are no material  administrative or judicial proceedings arising
under such laws or  regulations  pending  against  the  Company.  The Company is
unable to assess or predict the impact that  compliance with  environmental  and
pollution  control  laws  and  regulations  may have on its  future  operations,
capital expenditures, earnings or competitive position.

Tax Laws

     The  operations of the Company are affected by the federal  income tax laws
contained in the  Internal  Revenue Code of 1986,  as amended (the  "Code").  In
general,  the  limited  partners of the Company  will  generate  income from the
receipt of the  royalties  and net profits  interests  and will be entitled to a
depreciation  deduction.  Net income, if any, will generally be characterized as
portfolio  income  under  the Code and  will be  taxed  in the  same  manner  as
dividends and interest.

   
     Partnerships  with  interests  that  are  "publicly  traded"  are  taxed as
corporations unless at least 90% of their income is "qualifying income." Passive
income  or  loss  from  Publicly  traded  partnerships  that  are not  taxed  as
corporations  generally  cannot be applied  against  passive income or less from
other  sources.  As  stated  in  Item  5 of  this  Annual  Report,  there  is no
established  public  trading  market  for  the  Company's  limited   partnership
interests. In addition, the Company derives more than 90% of its income from oil
and gas activities,  which  constitutes  qualifying income within the meaning of
section  7704(d) of the Code.  Therefore,  the Company should not be affected by
the publicly traded partnership rules.
